The Billion Dollar Startup Club

The Wall Street Journal and Dow Jones VentureSource are tracking venture-backed private companies valued at $1 billion or more. See how the club has expanded since the project began in January 2014 and select companies to learn more about each.

Note: This chart only includes companies that are privately held, have raised money in the past four years and have at least one venture-capital firm as an investor. Excluded from this list are companies that were majority-controlled by an institutional investment firm at one point. Only valuations confirmed by VentureSource or The Journal are included, based on direct investments, not secondary deals. The chart will be updated as new information is reported.
